two Perlin noise generators in javascript. The simplex version is about 10% faster (in Chrome at least, haven't tried other browsers)
// Ported from Stefan Gustavson's java implementation
// http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf
// Read Stefan's excellent paper for details on how this code works.

Problem:
You have a javascript array that likely has some duplicate values and you would like a count of those values.
Solution:
Try this schnippet out.

A slightly modified implementation of Ken Perlin's improved noise that allows for tiling the noise arbitrarily.
public class Perlin {
public int repeat;
public Perlin(int repeat = -1) {
this.repeat = repeat;
}
public double OctavePerlin(double x, double y, double z, int octaves, double persistence) {
double total = 0;

Going from Lua 5.2 to PICO-8's Lua

This information applies to the PICO-8 0.1.6 release.

This document is here to help folks with a proficiency in Lua understand the limitations and discrepencies between Lua and PICO-8's Lua.

You can always view the manual or yellowafterlife's extended 0.1.1 manual.

General

  • anything written in uppercase the PICO-8 editor or .p8 is made lowercase by the editor. → editing the .p8 file directly can work
  • print(function() end) outputs the string function instead of the string function: 0x0000000.
